Determine a length of time for the game. 5 minutes works well. Leaf catch is best played in the fall in areas with a healthy population of trees but not evergreens. Players wait for a leaf to drift downward from the treetops and attempt to catch it before it touches the ground. The player who catches the most leaves in the given time period wins. You can also play until the first person catches five leaves. If time is no barrier, you can wait for the first person to catch ten leaves. Chances are it will take longer than you think to catch that many.
